A Massive Hot Jupiter Orbiting a Metal-rich Early M Star Discovered in the TESS Full-frame Images
The Astronomical Journal, 2023 Observations and statistical studies have shown that giant planets are rare around M dwarfs compared with Sun-like stars. The formation mechanism of these extreme systems has remained under debate for decades. With the help of the TESS mission and ground-

Global trends in winds of M dwarf stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT M dwarf stars are currently the main targets in searches for potentially habitable planets. However, their winds have been suggested to be harmful to planetary atmospheres. Here, in order to better understand the winds of M dwarfs and also infer their physical properties, we perform a one-dimensional magnetohydrodynamic ...

Mass Production of 2021 KMTNet Microlensing Planets. III. Analysis of Three Giant Planets
The Astronomical Journal, 2022 We present the analysis of three more planets from the KMTNet 2021 microlensing season. KMT-2021-BLG-0119Lb is a ∼6 M _Jup planet orbiting an early M dwarf or a K dwarf, KMT-2021-BLG-0192Lb is a ∼2 M _Nep planet orbiting an M dwarf, and KMT-2021-BLG ...

The M dwarf problem: Fe and Ti abundances in a volume-limited sample of M dwarf stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We report iron and titanium abundance measurements from high-resolution spectra in a volume-limited sample of 106 M0 and M0.5 dwarf stars. The sample includes stars north of the celestial equator and closer than 29 parsecs. The results imply that there is an M dwarf problem similar to the previously known G dwarf problem, in ...
